IoS, internet of space, A zero power device connects you anytime anywhere with protected communication, no carriers, no power grid, yes gridless infrastructure less secure connection.

My first thought about the nano probes is that we should be looking at incoming space particles for the same thing sent from elsewhere in the galaxy. If we thought of it then certainly other advanced life forms would have too. What if they are already here?
True Tom - though chances of happening on one are probably rather small just given likely density in any given volume of space. Another question for me is how does a nanoprobe beam a message back? How does something that small generate any energy at all and how does a beam from 4-6 light years away have any juice at all by the time it gets to us (~1/r[SUP]3[/SUP] energy dissipation for a conventional signal, somewhat better for a laser, but again, how do you fit a laser into something that small?). I know it has solar sails, but still, that's not an easy problem.
Just to be obsessive, I seem to remember that a laser shot at the moon spreads to about 1 mile diameter when it hits the moon. Scale that up for a laser shot from ~4 ly away. 4ly = ~25.10[SUP]12[/SUP] miles. The moon is about 25.10[SUP]4[/SUP] miles away. So the beam should spread to ~10[SUP]8[/SUP] miles diameter which is about the radius of the earth's orbit around the sun. Would need a pretty sensitive detector to pick that up even if you could shoot a sufficiently intense laser beam from that nano-satellite.
Maybe someone wiser in space communication tech than me already knows the answer to this?
